You're lucky, although, for future reference, putting it in rice with a slow fan is much better than blowdrying it. I'm not exactly sure why, but people have had trouble after blwodrying their electronics, but then they're fine if they put them in rice. Worked for my Chocolate 3!

Interesting. I didn't know you could see the liquid strip--but I peeked into my 3G's headphone jack with a flashlight and sure enough, I think I see it. Makes me worry about an accidental raindrop hitting at the right angle! I do use the iPhone for a few seconds in light rain sometimes, trying to end a call or whatever.
